AUTOTJIATIC OILING- DEVICE.

Application med ociobe 1c, 1923. semino. cenere.

.To all 'whom 'it flung] concem:

Be it known that I, CHAnLns C. SrnnnN,

a citizen of the United States, residing at Detroit, in the county oi' `Wayne and State 5 of ll'lichigan, have invented a certain nen7 and useful Improvement in Auto-,matic- Giling Devices, of which the following .is a

.'ffull, clear, and exact description, reference' being had'to-I -the accompanying draivings. Recent years have-witnessed the 1ntroduction and Widespread use' ot' mechanical power :in establishments not provided with attendants skilled in the operation and maintenance of power devices. It is obvi# ous that under these conditions it is essential that .these power devices require the mlnimuln" attention vboth for operation and maintenance. Hereto'ore vvarious modifications have been madetopartially accomplish this object but so far as am aware at the p'ii'esent time there has been suggested no satisi'factory method of supplyinpr oil to the machinery over a long period o'fi time. My invention provides means to accomplish this result. .in the-drawings accoinpanyiug,l this specific-ation and forming a part thereot` I have shown, `for purposes of illustration, certain physical-ernbodiments which my in.- ventive concept may assume and, because the electric motor is proba-bly thepower device most 'frequently encountered in establishments of -.the type herein considered, I have shown allbut one ot these illustrative einbodiments as applied. to an electric motor. In these drawings: Figure 1 shows one form of my invention adapted for use With a power device enr ploying 'a packed oil receptacle, While Fiffures 2, 3, and 4i are sectional views shoc'wnig modified forms of my invention.:

The'preseiit application is a continuation' in part of my application Serial Number 643,518 tiled June' 5, 1923.-

Under certain circumstances it may be convenient to employ a container other than.

l the usual oil can'shown in said copending application, and particularly a container of the type'in which. oil may be purchased in quantities,`-and in Figures 1 and 2 herein l have shown installations designed incre par ticularly to receive such containers and for 'purposes' of illustration have slaown these installations as adapted for use with that typegof power device provided with oil cups rather than that type which is provided with oil wells although it will be readily appar ent that the installations shown in Figures l and 2 herein may beicniployed as modifications of the installation shown in Figures 1 and 2 of said copendin'g application just as readily as they may be employed as niodi iications ot the installation shown in Figure 3 .of said copending applic-ation. The installation shown in Figure 1 com prises a iitting 7 0 provided -with a duct 71 arranged to enter Within. an aperturcf in the'upper end 59 of the oil cup 51 and sup: port the entire fitting 70 from the oil cup 5 1 by means of screw threads '72 and 6l carried respectively bythe outer surface of the duct ,71 and the iniier surface of the aperture 58 of the oil cup 51. This itting 70 is provided above the duct 7l with a reccptacle'Z-B formed bv a tubular extension 74 rising above the uct 71 and adapted to receive the cap 75 ot :in oil receptacle 76 and in this manner support the container 76 in operative position. At a point below the lower lace of the cap 7 the fitting; is interrupted, by the entrance of a duct` 7i" lea-ding from tlie-receptacle 7Std the atmosphereln employinpjA this installation it will be found convenient, after-forming in -the cap 75 an aperture l755, to remove the cap "i5 from the container 76 and position therein a sinple valve mechanism which may consist of an ordinary nail 79 inserted through a dislr 80 ot any suitable material such as cork or rubber and operable, While the conta-iner 76 is being p sitioned Within the fitting 7G, to prevent t e lovv ot oil 'from the container 76 until the container it has been inserted into the iitting 70 to auch an tent that the head of the nail "(9 strikes the lower face off the receptacle 73 after which further' insertion of the container causes the nail 79 to lift the disk S0 away from its sealing position across the aperture 78 and freely open the aperture 78.

It will be understood that atterthe con tainer 76 is thus positioned upon the fitting 70 oil vwill flow from the container nntii the oil level. Within the receptacle 73 rises above the opening into the receptacle .73 of the duct 7'? and in this manner cuts oil the supe ply of air into the container 76- and tlxereby terminates the ioiv of oil from the container 76 until such time the level ot the oil icc within the rcoeptaclo 73V iiells below the openin'v ot the duct 7?" into the receptacle 73 et liicli time the action will be repeated to bri-ingr the oil to its previous nigh level.

The installation disclosed in Figure 2 1s identical in construction and operation with ner in *whichr the duct 29 is tapped there-i into, provided with a. screw threaded upwardly opening aperture 82 arrenged'to receive e. correspondingly screw tlireeflled 4neel:

83 on a, container Se, and providclil adjecent 'the opening 232 with e vent 85 opening to the atmosphere. The operationf this embodiment of my invention is in ell respects similar to the operation of the embodiment disclosed in Figures l :ind of said copending application.

The installation disclosed in Figure l shows the oilin apparatus disclosed in Fig;-

, 'ure 3 applied to the oiling of an idlerpulley l556 rotating between e supporting member 8( and the heed S8 of the stud 89 which acts es the hearing tor the pulley 8G end is secured to the support 5?7 by means et c stein 9U which pes-ses through en aperture 91 in the support #ligand is screw threaded to cooperate with :i nut 92 arranged to clamp the supporting .member 87 between' itself and the shoulder 93 of the stud 89. ln this ins elletion the fitting 81 is inserted into the ew threaded opening: 94 in the end o'l the stud 89 to permit the oil Yfrom the receptacle 84E to flow into the cavity 95 Within the. stud 89 and from this cavity 95 through t duct 9G onto the hearing surface.

ln the installations shown in'Figure 3 and in Figure i the oil will ilorv from the receptacle 84 into the fitting: Sl until the oil (seuls the vent 85 whereupon further iiow will be prevented until the oil ,level drops below the entrance of the vent S5 into the itting 8L It will lie apparent to those skilled in the art that l" have provided a simple and satisfactory method of supplying ail-erge quan-V tity of oil to devices of tlietype herein considered and particularly to electric motors therefore illustrative only 'and my invention is not limited 'thereto but on the-contrary conipreliends any installation arrange-d to accomplish the objects of my invention-by equivalent instrumentelitiec.

I claim:

An oilingr device comprising en oil. con.

teiner of the type having :in outlet passageway screw threaded on 'its exterior to receive :i cooperetingly screw threaded closure member;` a iitting having un' inlet passageway screw threaded interiorly and cooperatingly receiving eid screvwv threaded pessugewey end thus supporting said container 'from said {itt-ingr., provided with chamber :into which said. outlet passageway extends, provided with nu opening` to the exterior disposed above-the level of the opening of said outlet pussegewaynd above said cham;- ber, and prgyifded Wit-h an outletopening emerging tlill'dugh e, duct-like projection arranged to lieinserted into theinlet opening ot' an oil. cup; and an oil cup'into tlie'inlet openingci which said. projection is operatively secured. i
